Frequently Asked Questions

How much difference do levels 0–9 make?
Level controls how hard the compressor searches for repetition: on text, 9 versus 6 usually saves 1–5% while taking up to twice as long; on already-compressed media, no level helps. Default to 6; reach for 9 with many small text files.
Why did zipping my photos barely shrink anything?
JPEG/PNG/MP4 are already compressed — their entropy is spent, and ZIP finds nothing more while wasting time. To actually shrink media, transcode (images to WebP, video at lower bitrate); do not re-zip.
Are there size limits when packing in the browser?
Nothing uploads, but memory bounds apply — keep total input around 250 MB; larger archives belong to system tools. The browser’s advantages are privacy (files never leave the machine) and consistent cross-platform behavior.
